I have a K. Martin Lathe with a bad starter. I would just replace the starter but find that it is no longer available. For the price of a new starter I could buy a 5 HP VFD and use that to control the motor. Is this a viable option or would a VFD not work well with a lathe? If it will work, what should I look for when purchasing the VFD? I have looked at a lot of information here ant at the manufactures sites but am not sure I understand anything at this point. Any help would be appreciated.
